This should not be underestimated. From the reports we've seen so far,
a very sizable fraction of people who find this kind of failure with 8.3
find out that their application was doing something unexpected in the
cases where it happened. If you've got as many failures as you suggest,
I'd be willing to bet that some of them are bugs in your code, not just
reliance on an implicit feature.
